Question about Isuzu Hombre

My 98 isuzu hombre 4.3 wont start when cold..only if you prime carb does it start and will stay running after it warms up. when you shut it off and try to restart after an hour it will not start. Have changed the fuel sending unit a month ago and worked well for the month.. any leads as what may be wrong?

The solution to this problem is particullarly illusive, and difficult to access without having the vehicle present to exstract additional information. Chances are the issue stems from a simple root cause. Such as a faulty intake air tempurature sensor, or an intermittent open in the powertrain control module. Take the truck to a trusted automotive repair facility and pay for a diagnostic analysis. Also ask that the vehicle be kept over night and for the diagnostic accessment to be done in the morning when the engine is cold. This will help simulate the condition.

Isuzu 4JA1 starts and immediately goes off, broken priming pump is this the problem? started after service


It could also be that the fuel filter is plugged, allowing only a small amount of fuel to carb Hence it starts but wont stay running.

Losing prime to carb after warm up


Check the fuel pump pressure. IF this is heat related, it could also be a bad gasket causing a vacuum leak. The other thing could be the fuel line is getting too hot causing the gasoline to create a vapor lock.

Engine wont start without priming with gas first, then runs well


i have the same problem on a 98 jimmy 4.3 4x4.
i replaced the fule pump and have good pressure.
new wiers & coil (good spark) no MIL & no codes.
will only start when primed. it will run & drive all day
with no problems.
but once it has been turned off (warm or cold) i will
have to prime it once again to start it.
i have another engine that was in it before it spun a bearing.
it ran fine so i know all parts are good.
i swaped the mass air flow and throttle body but i still have
to prime it everytime to start it. am i forgetting something?
should i swap out the intake with the injectors?
any help would be sweet. thanks.
